Anyone using current production KT66's in there JTM45 or any other amp? I know little about the Tung-Sol/JJ/Golden Lion stuff, so any help is appreciated....

I recently got an amp that uses KT66s so I did some internet searching.
about this very question

What I came away with is that the Valve Arts seem to have the best
version of a KT66 in terms of tone and reliablity.

Opinions do vary tho' so ...

In my single ended GT soul-o I tried the Russian Groove Tubes and the Valve Arts.

To my surprise, I prefer the GT.

The Valve Arts proved to be a little too hifi in this particular amp.

Groove Tubes and Valve Arts/Shuguang are the only companies with true reproduction KT66s. Groove Tubes current production KT66s are the same as the Valve Arts I believe. The GT KT66HP has been discontinued for quite some time now. The Tung Sol and JJ reissues are a different tube in a KT66 bottle. I thought the Tung Sols were cool sounding, but sound more like a 6550.
